Application tiled J'nne 4, 1900. .Serial No. 13,935. (No model.)

and State of Massachusetts,have invented cerf tain new and useful Improvements in Bells;

and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being hadvto the accompanying drawings, and to the let-ters of reference marked thereon, which form apart of this specifica` tion.

My invention relates to the bells placed in floors of vehicles-'such as automobile carriages, cars, rbc-to be operated by the foot; and its object is to make aV bell that shall be simple in its construction and that will give a prolonged and eective ringing with a simple pressure of the'foot. It is fully described and illustrated in the following specication and the annexed drawings.

Figure 1 shows oneof the gongs, the other having been removed to show the internal mechanism. Fig. 2 represents a vertical section ofthe bell and oor-fastenings to the tioor, taken down through the center of the bell. Fig. 3 represents the stationary plate with the swinging plate and the hammer, both pivoted to the stationary plate. Fig. 4 is a vertical section of the parts shown in Fig. 3,taken on line 4 4 in Fig. 3. Fig. 5 is a plan View of the stationary plate. Fig. 6 is a plan view of the swinging plate. Fig. 7 is a top view of the hammer. Fig. 8 is a front edge' view of the hammer. Fig. 9 is a side elevation of a part of the inner tube. Fig. 10 shows a vertical section of a part ofthe inner tube, taken on line lO 1Y0 in Fig. 9. Fig. ll isa separate view of the plug and notched plate.

The constructionand operation of the bell are as i'ollows: In Fig. 2, C is the upper gong, attached to the bottom E of the vehicle by means of a hub W on the outside, which hub has a horizontal iian ge d', that iits up against the bottom of the vehicle and is held fast there by means of bolts that pass down through a plate cl on the upper side of the floor and.

throughthe iiange of the hub. The lower gong C is attached to the upper gong by means of an inner tube N, which passes down from the plate d through the two gongs C C into a nut below the bell. The two gongs are made `fast on this tube N either by being forced on or by means of screw-threads made in the holes or the gongs and on the outside of the tube N. The edge of the upper gong is extended out down by the edge of the lower gong to keep the dirt out from between the two gongs. (See-Fig. 2.) The upper gong C has an inner hub c', and a lower gong G has an inner hub c, and between these two hubs the moving partsof the mechanism are held. 4A plate D (shown in Fig. 5) is made fast on :the top of the inner hub c, (see Fig.l 4,) and to this stationary plate D a swinging plate B is pivoted at Z9, and a hammer F is also pivoted to plate D at a. A pin h, (see Figs. 3 land 4,) fast in the'haminer F,'projects up through the opening r in the plate D,so as to enter a slot in the free end of the swinging lever B and be moved by that lever when it swings. The inner tube N has a slot e made through-both sides (see Figs. 9` and l0) oppo- `site the space between thetwo inner hubs o and c, and a sliding plug R, having a plate n with teeth on each edge held fast in a slot in it, (see Fig. 11,) is held in the tube N, so that` the teeth will project through the slots e e. (See Fig. 1Q.) The swinging plate B has an openingj' in it near. its pivot t), and there are two projecting teeth g, one on each side of the opening, (see Fig. 3,) that extends in s o as to engage with the teeth on plate it, andwhen the plug R is pushed drown by the pin J the teeth, which are made on each side to come opposite to a space on the other'side, will throw the plate B from one side to the other alternately and cause it to vibrate thehammer F in like manner by the pin h and strike the gongs first with one end and then with the other. The end of the hammer F is bent down to strike the gong C', while the other end is left straight to strike the upper gong C. The pin J, (see Fig. 2,) by means of which the ringing is' accomplished, is put in the tube N, so as to rest on the plug R, and is held from coming out too far bya spring t, held in a groove in the side of thel pin and arranged so that the upper end of the spring shall catch under the plate d. (See Fig. 2.) An open spiral spring H is placed IOO in the lower part of the tube N under the plug R, so as to throw the plug and pin up after they have been pressed down by the foot on the head of the pin and cause the teeth on the plate n to ring the bell both when the pin J is pressed down and when the spring pushes it up again. f

Having thus described my improvements, I claim as my invention and desire to secure by Letters Patent- 1. In a bell the combination of two gongs having hubs on the inside, a tube connecting the gongs by passing through said hubs and having slots in its sides to connect the operating device with the ringing mechanism, substantially as described.

2. In a bell the combination of two gongs having hubs on their inner sides, a tube connecting the gongs by passing through said hubs, and having slots in its sides to connect the operating device with the ringing mechanism, a stationary plate fast on one of said hubs, a hammer pivoted on the stationary plate, a swinging plate pivoted on the stationary plate and having a notch in one end to receive a pin fast in the hammer, mechanism sliding in said tube to operate the swinging plate, substantially as described.

3. In a bell the combination of two gongs having hubs on their inner sides, a tube connecting the gongs by passing through said hubs, and having slots in its sides to connect the operating device with the ringing mechanism, a stationary plate fast on one of said hubs, a hammer pivoted on the stationary plate, a swinging plate pivoted on the stationary plate and having a notch in one end to receive a pin fast in the hammer, a plug to slide in the tube, a toothed plate carried by .pivoted to said stationary plate, a swinging plate pivoted on said stationary plate connected to said hammer, with vibrating mechanism actuatedthrough the center of said gong, substantially as described.

6. In a bell, the combination of two gongs having hubs on their inner sides, said gongs being connected together'by said hubs, a stationary plate fast to said hubs, a hammer pivoted to the outer end of said plate, a swinging plate also pivoted to said stationary plate and connected by an arm to said hammer,with

a sliding cam and spring actuated through the center of said gong, substantially as described.

7. In a bell,the combination of two gongs, a tube connecting said gongs, a slot in the side of said tube through which to connect the actuating device with the ringing mechanism, means for actuating said ringing mechanism through the center of the gong, substantially as described.

In testimony whereof l have hereunto set my hand this 29th day of May, A. D. 1900. CARL A. BRINK. In presence of HOWARD E. BARLow, BENJ. ARNOLD.
